SCALE.

Application filed. February 25, 1908.

To all whom it may concern:

Be it known that ii, SAMUEL COOPER, a citizen of the United States, anda resident of Nunda, in the county of Livingston and State of New York,have invented a new and Improved Scale, of which the following is afull, clear, and exact description.

The invention relates to measuring instruments, and its objectis toprovide a new and improved weighing scale, arranged to permit the minuteadjustment of the poise to insure accurate weighing and to allowconvenient reading of the result.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in bothviews.

Figure l is a plan view of the improve ment, part. being broken out, andFig. 2 is a side elevation of the same, parts being broken out.

On the base A of the weighing scale are arranged bearings B engaged bythe knife edges of the pivot pin C, secured on the beam D, adapted tocarry at one end the load by the use of a suitable support, such as apan, scoop, platform or the like, held on a frame E mounted on the beamand provided with a receptacle F for containing weights em ployrd fortruing the scale.

The poise G for the beam D is made in the form of a cylinder, having itshorizontal axis disposed transversely of the beam and the said poise Gis adapted to roll lengthwise of the beam, to bring the latter intoequilibriuinwhen weighing. For the purpose mentioned the poise G issecured on a shaft H, provided with pinions 1 in mesh with racks J,secured to or formed on the beam D a distance below the top thereof, asplainly indicated in Fig. 2. The outer ends of the shaft H are providedwith knobs or handles K, adapted to be taken hold of by the operator,for turning the shaft H, the pinions 1 and the poise G, with a view toroll the poise G along on the beam D, nearer to or farther from thepivot pin C,

according to the load supported on the frame E, to bring the beam Dfinally into equilibrium. It is understood that by hav- Specification ofletters Patent.

ing the pinions I in mesh with the racks J, a positive forward orbackward rolling of the poise G is had, to enable the operator toquickly and conveniently bring the beam D into equilibrium.

On the shaft H are arranged washers L, pressed on by springs N coiled onthe shaft H, between the washers L and the corresponding ends of thepoise G, the said washers pressing against the inner faces of the racksJ and the upper portion of the beam D, so as to hold the poise G- in theadjusted position by the frictional contact of the washers with theracks J and the upper portion of the beam D. The poise G is provided atits peripheral face and at or near each end with scales G, G the topmarks of which are adapted to register with corre sponding marks onscales 0, preferably formed on a plate 0, secured to the top of the beamD. The scale 0 is divided to represent pounds and subdivisions inquarter ounces, and the scale 0 is divided to represent pounds and halfounces, and the graduations G and G are similarly arranged to representquarter and half ounces. Owing to the fact that the poise G is ofgreater diameter than the gear wheel I, the circumference of the poiseis greater than the distance, which the poise travels in a completerotation and consequently it is necessary that the graduations of thescale of the poise be spaced farther apart than the graduations of thescale of the beam. The circumference of the poise is such that when itmakes one complete revolution it will have traveled a distance of a unitgraduation of the scale beam, that is, the poise G makes one completerevolution from one pound mark to the other. Thus by the arrangementdescribed, the graduation marks Gr, G on the poise Gr at all timescorrespond to the graduation marks of the subdivisions on the scales 0,0 As shown in Fig. 1, the beam D is provided with an opening D, throughwhich the poise G is visible from above, to allow the operator toconveniently read the result on either of the scales 0 or 0 The free endof the beam D is provided with a transverse bar P adapted to rest on thecushion top Q of a base Q, erected on the base A, to limit the downwardswinging v motion of the free end of the beam D. The frame E is providedwith a downwardlyextending rod R, having its lower slotted end Bstraddlin a )in {'5 attached to the 5 base It, so as to limit thedownward swinging motion of the load end of the beam.

From the foregoing it will be seen that the operator, on taking hold ofeither handle K, can conveniently and readily roll the cylindri :alpoise G lengthwise along the beam 1 to bring the latter intoequilibrimn. the operator being enabled to quickly and conveniently readthe result on the registering graduation marks of the tales G, Gr, 0', O

illaving thus described my invention, 1 claim new and desire to secureby Letters Patent:
